A must have for any serious college or club training program. Great for speed/power development and also a great teaching tool.
Having been a swimmer all my life and a coach for the last 11 years the stretch cords are a great way train. I coach high school age kids and they love doing these. Its like a game to them but what they havent figured out yet is thats its actually a harder workout than if they were in swimming normally. The sprinters really love them!!! I tend to put the boys on the green cords and the girls on the yellow cords and let them go at it. I highly recommend them.
The first day I used this item with my team - the stretch cord broke when doing some speed work. The inside cord broke off from one end. The idea of the stretch cord is awesome - the particular one I used was not well made.
